Bruce,

I was on last night, and heard you a couple of times with a very strong signal. Other times fairly weakly. One thing to check would be your antenna directions. You will have a fairly narrow beam width, especially vertically, with those antennas. I recalibrate my array at least twice a year, summer and winter. I especially notice the difference when the mode S downlink is active, as my dish is the tightest of my antennas.
